darTZeel NHB-108 Model 2 - The Best Stereo Amplifier In The World Just Got Way Better!

Did you go one XLR per channel, then? Would love to see a pic

Measured some screws on my 18NS power supply and got lower impedance on some of the screws next to the IEC, but if I remember correctly you (or perhaps someone else here) got the nod from darTZeel to use one of the ones along the PSU’s top panel. Which one specifically?

(Love love love my darTZeels. Just fantastic gear.)

the best in the world, that's funny, there is NO best, I will keep my Burmester

I'm sure your Burmester is fantastic. Would love to hear one one day. It might even tie in nicely to a possible shared love of Porsches

(If the "best" you're referring to is the one in the thread title, I'll agree with you that hyperbole and absolutes aren't often helpful. But that thread title was also written five years ago. We've moved onto way nerdier things, like how to ground the thing ;-))

Check out post #58 in this thread
I measured ~0.1ohm resistance using this screw.

Probably better; but doubt it will make a difference, to use the circled screw pictured below instead, but note that it’s very short, so you will need a longer screw, and you’ll need to secure the nut from the inside while you tighten It. Note that it’s connected to the chassis/case, and I used the post you see to the left of the AC connector.

The reason why the ground makes a difference on the preamp is because the signal/chassis ground is still connected to the AC mains ground, even though it’s battery powered. This is must be why @Mike Lavigne noticed that the AC cord makes a difference on the 18NS. Note that you can set the ground lift to on, which may make this unnecessary; but I haven’t changed it (My ground jumper is “Connected” inside the preamp).

Will post a photo of the back of the amp shortly.

Ha ha, yes — I saw post #58, but I wasn’t 100% clear on which screw was shown. Too zoomed in

The internal pic you just posted circles the screw where I got the lowest measurement, which is encouraging. Whether or not the screw choice makes a difference here is another thing entirely, of course.

Very interesting re: Mike’s findings. Will be a pity if my mate who just bought a Model Two and 18NS needs one more nice power cable

I used the screw on top of the case, in the upper left corner - you can see the screw post in the image above. It’s the closest top cover screw to the AC inlet.

You can see the XLR Omega ground cables here.

Amazing. Thanks very much indeed. Will be interested to see how this pans out
